| 摘要 |
The invention relates to equipment for magnetic resonance tomography where, for the formation of physiological test signals, an electronic measuring system with an electro-optical transducer is arranged in a shielded cabin receiving the magnetic resonance tomograph. From this transducer a beam waveguide leads to an electronic processor with an opto-electric transducer provided outside the cabin. At the input, the electronic measuring system comprises a radio-frequency filter, a following wideband amplifier and thereafter, before the electro-optical transducer, a slew rate filter.
